Osteodontokeratik culture and its makers.

Dart’s claim

At Makapansgat Limeworks Dart described a non-stone industry. He read long bones as clubs, mandibles as saws and scrapers, canine teeth as projectiles, and horns as daggers. He called this osteodontokeratic (bone–tooth–horn) and gave it to Australopithecus prometheus, a name later folded into Australopithecus africanus.

• Site: Makapansgat, South Africa, in australopithecine-bearing cave breccias.
• Background: Dart’s Taung child (1924) had already placed australopithecines on the human side of the family. In the 1950s the osteodontokeratic papers tried to give those hominins culture without stone tools.
• Story attached: Hunting, and even interpersonal violence. Robert Ardrey’s later “killer ape” popular writing drew on this mood, even though Ardrey was not the field scientist.

Why the idea was tempting

If early hominins made tools from carcass parts, culture would be older than the Acheulean handaxe, and hunting could be pushed deep into the Pliocene. That fitted a mid-century taste for “man the hunter” and for African origins after Taung.

The critique that stuck

C. K. Brain, especially in The Hunters or the Hunted? (1981), showed that many supposed tools are the signature of leopards, hyenas and cave collapse, not of artisans. Tooth marks, spiral fractures and the over-representation of certain bones match carnivore dens and geological concentration. A famous related image is the leopard puncture in some australopithecine skulls: the hominin was prey, not always hunter.

The fossils at the site remain australopithecine. The culture does not survive as a real tool tradition.

• Lesson: Hominins present in a cave are not automatically tool-makers. Osteodontokeratic is a taphonomy parable, not Africa’s first industry.
• What remains useful: The debate professionalised faunal analysis. Hunting versus scavenging, and how cave assemblages form, still rest on Brain’s ground, not on Dart’s clubs. Later accepted bone tools, such as some from Swartkrans, are a different and much more cautious file.
